"Well, ah...That and you haven't walked away. I don't take you for someone who wastes time, if you'll forgive my assuming."
He's practically sweating bullets by now, and looking Lightning in the eye gets harder by the second. Why oh why had he opened his fat mouth and insulted such a formidable woman?

"Um, I know it won't mean much, but I'm truly sorry for, ah...A-angering you with my words. Haha, you've actually really helped me in figuring out what this place is and this is how I thank you..."
At least Gordin has the grace to look ashamed of himself, nervy as he is at the moment. Sure, words are cold comfort after the fact (and it doesn't bolster his confidence when he's feeling cut down to size), but there's a genuine desire to make up for his continuous verbal blundering.

It's the least he can do, really.
